QTR-MD-03RC Reflectance Sensor Array: 3-Channel, 8mm Pitch, RC Output.This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9 V to 5.5 V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high-reflectance objects are generally detectable out to around 30 mm. This version features the traditional-style QTR sensors without lenses. Specifications: * Pitch x sensors: 8mm x 3 * Size: 21.0 x 20.0 mm * Output: RC (digital) * Max current LED: 30mA * Max current board: 62mA * Optimal range: 5mm https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2025-01-23 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2025-04-06 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2025-04-09 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2025-06-03 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2025-06-18 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2025-09-28 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-01-03 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-02-07 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-02-12 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-02-15 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-03-04 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-03-11 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-03-14 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-03-18 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-03-31 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-04-04 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-04-12 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-04-16 https://elecena.pl/product/27741663/pololu-qtr-md-03rc-reflectance-sensor-array-3-channel-8mm-pitch-rc-output 2026-04-18
